SMUT-MACHINE.

Specification of Letters Patent No. 11,800, dated October 10, 1854. i

T 0 all whom t may concern Be it known that I, THOMAS B. VooD- and operation of the same, reference being had to the annexed drawings, making a part of this specification, and in which- Figure l, is an external view of the machine in elevation; Fig. 2, is a' vertical sec* tion of the open screen or curb, fan case, and wind passages, the Ventilating cylinder, fan

and shaft not being bisected;` Fig. 3 is a horizontal section of the Ventilating cylinder and screen, or curb, taken at the line X, X, Fig. 2; Fig. 4 is a plan or top view of the upper disk of the Ventilating cylinder. To enable others skilled in the art to make and use my invention, I will proceed to describe fully its construction and operation.

A, represents the frame of the machine, having a vertical shaft- B, in the center on which is placed the driving pulley C, Figs. l, and 2, the shaft being stepped at (a). On this shaft B, is placed the Ventilating revolving cylinder formed by bolting or securing in any proper manner the fiuted columns (o) between the two horizontal disks or heads D, E, see Fig. 2. There are nine columns represented in the drawings but I do not confine myself to any particular number. Six columns are placed about equal distances apart near the edges of the two disks or heads, and the other three are placed nearer the center of the heads or disks. By referring to Fig. 3, an exact idea will be formed of the manner in which the columns are constructed and placed in the cylinder. The columns are about square and are each composed of t-wo angle plates, l and 2, corrugated, ribbed, or fluted, as represented. The sockets in the plates D and E for the reception of the columns, keep the two parts of each column together in the proper relative position. One angle of the square of each column faces outward; this is so arranged that the columns as the cylinder revolves will create a blast and also act more eiiiciently upon the grain. The columns may be constructed of chilled castiron. The upper disk or head D, has grooves cut in its upper surface or face, the grooves being so arranged as to form diamond shaped projections, in Fig. 4. The grooves are represented by straight'lines. The lower disk or head E, has'three circular openings (c) (c) C(lo) through which 'air passes into the cylin- F, is the perforated curb, Figs. l, 2, and 3, this curb encompassesthe cylinder and is perforated with oblong openings, the lower end of the curb rests on the edge of a circular plate G, see Fig. 2, said plate having a flanch turned up on its edge, the end of the curb being within the flanch the plate G, rests on cross pieces of the frame and has a circular opening f, at its center, there is a space between the under surface of the lower disk or head E, and the upper surface ofthe circular plate G, and there are radial arms (d) on the under surface of the disk `or head E, which serve to sweep o if the grain that falls on to the plate Gr, and passes it down the spouts H, H, into the blast spouts I, I; on the upper end of the curb F, there is fitted a circular plate J, which is grooved on its under surface or face similar to the upper .surface or face of the disk or head D, shown in Fig. 4, it will be seen that there is a space between the under surface of the plate J, and the upper surface of the head or disk D, as will be seen by referring to Fig. 2, there is some space also between the inner surface of the curb and the edges of the heads or disks D, E. On the inner surface of the curb F, are bolted at equal distances apart vertical ribs or projections (c) Figs. 2, and 3.

K, is a horizontal fan inclosed within a suitable case and placed a short distance below the revolving cylinder, the fan is hung on the vertical shaft B, a blast of air is directed from the fan into each of the blast spouts I, I, a piece of wire cloth or a sieve (g) being placed over the entrances or passages that lead into the blast spouts which prevent the grain' from falling into the case of the fan. See Fig. 2.

The several parts are now described, and the operation of the machine will be shown, the grain is placed in the hopper L, motion being first given the vertical shaft B, which of course causes the cylinder, and fan to rotate, the grain passes from the hopper through the opening (It) in the plate J, and passes between the plate J and the upper head or disk D, into a chamber Y the under surface of the plate J, and the upper surface of the head or disk D, which form the top and bottom of the chamber Y, being grooved as already shown,the grain is scoured, by the rotary motion of the disk D, the dust being loosened and the smut broken, the grain then passes down between the curl F, and

the disk D, into a heating chamber z in which the luted columns (b) act upon theV grain throwing it against the ribs or projections (e) from which it rebounds and is again acted uponl by the columns, the column as the cylinder rotates creating a blast of air which enters the cylinder through the circular openings (c) (c) (a) see arrows, 1,v

the blast blowing out the dust and smut through the perforated curb, the grain then -i'alls upon the plate Gr, from which it is swept by the radial arms (al) into the spouts H, H, the upper ends of these spouts passing through the plate G, and being flush with its upper surface, the grain then enters the blast spouts I, I, the blast fromv the fan K, cleansing further the grain as it passes through the blast or current of air, the grain is conveyed into the proper receptacle by the spouts M, M, which are attached to the y lower ends of the blast spouts.

This smutfmachine is capable lof cleansing wheat, rye, and all kinds of grain that may be cleaned by vother machines in use, doing its work in a perfect-and effectual manner, the fluted columns4 facilitate greatly the cleansing of the grain, beating and pulverizing the smut and at the same time creating a blast by which yit is driven out of the cylinder, the grain also inpassing through the blast created bythe fan ,is further cleansed, and when conveyed into the proper receptacle is deprivedl of all ldust and impurities.

Having thus described my; improved smut .machine, what I claimtherein as new, and

THOS. B. VVOODWARD.
